Technical characteristics
Checker Hanna nitrate analyser for marine water (high range) HI782
The HI782 Checker HC (handheld colourimeter) is a simple, accurate and cost-effective way to measure pH in salt water.
Nitrates are a by-product in the nitrogen cycle. High amounts of nitrate in reef aquaria can lead to the growth of undesirable organisms such as algae and dino-flagellates, while deficiency of this compound can lead to starvation where SPS corals and other corals will show loss of colour or paling.
The HI782 Checker pocket colourimeter uses the Lambert-Beer principle to determine the nitrate concentration colorimetrically.
The HI782 is specifically designed for high nitrate levels in saltwater aquaria.
The range of 0.00 to 75.00 ppm is ideal for aquaria and marine biology.
what is included?
The HANNA HI782 checker is supplied complete with two cuvettes with lids, reagent powder for 25 tests, filter holder, paper filter discs (25 pcs.), 10 ml syringe, 5 ml syringe with tip, mixing vial with lid, battery and instruction manual.
Two bowls with lids
Reagent powder for 25 tests
how is it used?
Designed as a more accurate alternative to chemical test kits, the HI782 provides fast, accurate results in a few simple steps:
STEP 1. Zero the checker with your water sample.
STEP 2. Add reagent to the cuvette.
STEP 3. Insert the cuvette into the Checker.
STEP 4. Press the button and read the results.

HANNA checkers are small, portable and, above all, provide more accurate results than typical chemical test kits. Offering improved technology, their simple design allows for easy, uncomplicated measurement.
These digital photometers or test kits serve as a bridge between very simple test kits and professional instrumentation such as a calibrated photometer.
Conventional test kits are not accurate and depend entirely on the user viewing the colour, which is why HANNA has digitised this measurement and achieved accurate digital pocket colourimeters.
The innovative shape of the Checker makes it fit in the palm of the hand and in the pocket. In addition, the LCD display is easy to read, with an automatic shut-off function in case for some reason you forget to turn it off.
